EEEGIFIGATTLGN formin par: of Letters Patent No. 756,557, dated. April 5, 190%.,

Our invention has relation to rel'ieating-furnaces for glassware, and has for its object the provision of a furnace wherein glassware or blanks for the manufacture oi glassware of various characters may be rehected expeditiously, econoniaically, and satisfactorily to prepare them for suoscoucnt manipulation or treatment.

Our invention consists in the novel construc tion, combination, and arm: hereinafter described and cl In carrying" our inven tion into effect we provide a furnace substantially in the form of a vertical stack or chimney, and in. this furnace we arrange a carrier that traverses the fun nace from top to bottom and which is so con- 0 structed that it will support and carry a con- I siderable number of articles or blanks to be reheated, all the blanks or articles on. the carrier being successively brough t from the cooler to the hotter-part cl the l'lnnnce, so that While a large number of such blanks or articles are being; simultaneously heated they will be brought either sin fly or in pairs or groups to I set do" i r; in sucrone of the 1 ill l l sed c. 1 con- L- 1S o1- manlpulatlng Winks or artzcles-such, for 111- hcut attainable in the July 7,1903, Serial No. 16%,5'79. (N0 model.)

stance, as the finishing of the edges of completcly-formed articles by the mere action of the heat in the furnace-we do not wish to be understood as confining our invention to any particular manner of treating or manipulating the reheated blanks or articles.

Referring to the accompanying drawings, Figure 1' is a Vertical sectional .view of a furnace constructed according to our invention, and Fig. 2 an enlarged "sectional. View of a part of the carrier shown in Fig. 1. i

A designates the body of the furnace, which is constructed o'f'suitable material, such as firebrick, and substantially in the form of a square vertical stack or chimney. Within the i'urnace, at or near the bottom of the same, is a gas-burner B, by means of which the chimney is heated, or it can be heated in any other suitable manner. Sprocket-wheels G and D are arranged at the top and bottom of the furnace, and an endless chain E'passes'? over the sprocket-wheels and is caused to traverse the furnace from top to bottom by turning the wheel 1), which is mounted on a shaft d, having a handle (2, by means of which it can be turned. The sprocket-wheels are so placed that one side of the chain E is inside and the other outside the furnace, and the latter has an opening F in its side wall near the bottom for the passage of the chain and an opening G on the other side for the passage of a mold H, into which the blanks drop from the chain and in which they are blown to completed form. As shown in the enlarged View of part of the chain, Fig. 2, it consists of jointed lin *s, each alternate link being formed with lateral wings i 2 in which are pivoted swingingplates 1, having notches or recesses K for the reception of the blanks L. As it is intended to put the blanks on the chain at'the lower end of the same outside the furnace, the'swinging plates I are provided for the purpose of allowing the blanks to pass over the upper sprocket-Wheel. without falling" oil, the positionwhich the blanks assume while passing over the sprocket being clearly shown in Fig. 2.

. tration show only one sprocket-wheel at the top and bottom of the furnace. itaisto be understood that there are two s rocke -wheels, at each of these places, as usual in the conj'f.

struction of chain conveyers, so that tl1epiv-. oted plates, with the blanks thereon, will pass over the upper shaft of thesprockets C and avoid contact with the sprocket-wheels.

In Fig. 1 the mold His shown in position within the furnace ready to receive a blankwhich is slipping ofl" one of the links, and in order to cause the pivoted plate to tilt and drop the blank into the mold a tripper M/is provided which will contact with the inner end of each. pivoted plate as it reaches the point where. it is desired to discharge the blank-z When it is desired to deliver the blanksdn pairs or groups instead of one at a time, the

plates I can be made with two or more notches or an additional. chain can be provided and arranged to travel alongside the chainE.

The furnace being constructed and arranged as described is operatedin the following manner: The blanks are placed successively in the notches in the swinging plates and the sprocket D being turned by turning the l1andle d the chain will carry the blanks up on the outside and down the inside of the furnace,where they will besuccessively brought from the point of least heat at the top to the point of greatest heat at the bottom, and thus 'while a large number are being heated simultaneously they will be successively brought to the degree of heat required. As the blanks reach the lower end of the furnace the pivoted v plates I are successively'tripped by the tripper M and the blanks allowed to slide off the plates and into the mold H, which is then drawn out of the furnace and the blank blown therein to the desired shape, preferably by compressed air which is conveyed from a suitable source tiltrough a pipe N, having a cock 0,,for regulating the supply of ainand it-mouth or fitter P adapted to fit dow'nwyer *the neck of the blank.

- Instead of receiving the blanks directly in the mold they may be removed from the chain on forks, and being held in suitable blhwsnaps they can, if desired or necessary be Y still further heated at the glory-hole and then placed in the molds and blown.

. The vertical furnace and the manner in tripper adapted to tilt said plates substantially as described.
